Honeywell To Test Biofuel in APUs, Engines

Honeywell Aerospace is gearing up for biofuel tests on its APUs and engines this summer in a bid to stay ahead of the alternative fuel push. The company plans to run a business jet engine and an airliner APU fueled by a mix of jatropha and algae oils from sister company UOP, which has blended various fuels for more than 100 years. Honeywell director of advanced technology Ron Rich declined to reveal the business aircraft engine model slated for the biofuel testing, though he said that by the end of the trials both the Honeywell TFE and HTF-series engines will have run on the alternative fuel.
